![]() ![]() Asynchronous ProcessingĪsynchronous request processing may be required when creating/updating a resource is time-consuming. SOAP security is well standardized through WS-SECURITY, which is very much feature-rich and easy to implement into application code. Any further security should be additionally implemented at the server. It supports basic authentication and communication encryption through TLS. REST is based on HTTP – which itself is a very unsecure protocol. When binding to HTTP, all SOAP requests are sent through HTTP POST. ![]() SOAP also defines a binding to the HTTP protocol. ![]() REST is primarily used over HTTP and it makes use of HTTP GET, POST, PUT, DELETE, and PATCH methods for different CRUD operations. So, SOAP responses should be cached using information given in Response Caching Optimization Module. As HTTP POST is non-idempotent, it can not be cached at the HTTP level. SOAP, when using HTTP as the transfer mechanism, is sent via HTTP POST requests. The ETag header is a good way to implement caching providing you’ve got a cheap way to compute what the value should be. REST provides a good caching infrastructure over HTTP GETmethods thus enabling response data to be marked as cacheable or not-cachable. Normally, SOAP Web services are stateless – but you can easily make SOAP API stateful by changing the code on the server. Managing the state of conversation is the complete responsibility of the client itself. RESTful Web services are completely stateless. The point is that you can obtain the output you need in a form that’s easy to parse within the language you need for your application. REST can use the data in Comma Separated Value (CSV), JavaScript Object Notation (JSON), and Really Simple Syndication (RSS). SOAP relies exclusively on XML to provide messaging services, which can become extremely complex in some cases, e.g., accessing web service via javascript. REST is almost synonymous with HTTP, though REST specification does not mandate it. The SOAP itself is a protocol (over HTTP) for developing SOAP-based APIs. The choice of which one to use – largely depends on what really is required, from the business and an architectural point of view.īy looking at both their strengths and weakness in certain environments, as well as understanding your own project scope, you can make the most informed decision. SOAP and REST – both provide support for building SOA-based applications. REST can structure data into XML, YAML, or any other machine-readable format, but usually, JSON is preferred. REST – REpresentational State Transfer – is an architectural style that makes use of existing and widely adopted technologies, specifically HTTP, and does not create any new standards. SOAP – Simple Object Access Protocol – defines a very strongly typed messaging framework that relies heavily on XML and schemas. ![]()
